PRECOATED METAL SHEET, METHOD FOR PRODUCING THE SAME, AND CONTINUOUS COATING DEVICE

摘要

PROBLEM TO BE SOLVED: To make compatible at high level, both glossiness of a multilayer precoated metal sheet and adhesiveness of coating films to each other of the same, the multilayer precoated metal sheet being produced on a continuous coating line.SOLUTION: The precoated metal sheet having a plurality of coating film layers on one or both faces of a metal sheet 10 is provided in which the coating film layer includes: a colored coating film layer 111 disposed at the side of the metal sheet 10 and containing a coloring pigment; a pigment-concentrated layer 123 formed on the colored coating film layer 111, having a coloring pigment concentration higher than that average value in the layer 111 and increasing as heading for a surface layer side; a dispersion layer 122 formed on the pigment-concentrated layer 123 and having the coloring pigment concentration decreasing as heading for the surface layer side; and a clear layer 121 formed on the dispersion layer 123 and including no coloring pigment. The ratio d1/d2 of the thickness d1 of the clear layer 121 to the thickness d2 of the pigment-concentrated layer 123 is 1.7≤d1/d2≤4.7.SELECTED DRAWING: Figure 5
